To all whom it may concern:

Be it known that I, FELIPE GIROUD, a citizen of the Island of Cuba, and a resident of the clty of New York, in thecounty of New York and State of New York, have invented a certam new and useful Machine'for Cutting Paper-Box Blanks, of which thefollowing is a specification.

- This application fora-patent is'adivision of .my former application; filed the twelfth day of Qctober 1907, Serial Number 397139 an? pntltled'machines for wrapping various ar 1c es. 7

v This invention relates to machines for outting paper boxes.

forming and cutting ofi the blanks from a sup 1y stri of a er, said a er havin a unifbrm width. p p p p a g Other details are shown in-the acc0inpany=.

. of the cutting mechanism. Fig. 3 is a plan view of some of the parts shown 'n Fig. 2. Fig. 4 1s a sectionv on the'line 1V7 V of Fig.

1. Fig. 5 is a section on the line V'V of Fig. I '2.

Fig. 6 is a view illustrating the format1on of the blanks. Figs.'7,8 and 9 show successional steps in folding one ofthe blanks.

A continuous sup ly of -.paper 1 passes betweentwo quick rol ers 2 and 3, which rotate in bearingsformed on standards 4 forming part of the'mainframe 5. As the paper passes between the rollers 2 and 3, it is guided by flanges 6 formed on roller 2, into alinement with a drum '7. Drum 7 and another drum 8 actuates -means for making slits and creases in thepaper forming the blank, finally cutting off the blank and feedingit to a chute 9 as hereinafter described.

As shown in Fig. 6 a crease 10 is formed lengthwise of the blankya distance from-each margin determined by the shape of the box to be formed. At the centeriof the blank,

two slits 11 are 1 cut, extending from each margin to crease line 10 at a distance apart equal totheir length and creases 12 are formed across the center part on a line with slits 11: At'the lower end of the blank, a

crease 13 is formed crosswise, a distance from the endeq-ual. to the distance of creases 10 from the side imarginsyand two'slits 14 are.

cut extending from. the endto crease 13 on a paper blanks for use in the formation of 1 .drum 7, which force the paper into corre- The invention consists of mechanism for 1 line withcrease 10. ,The upper end of the blank is separated from the blank coming after, by a crosscut 15 extending the'full width of the paper. A slit 16 is cut extending from each margin to crease 10 at a distance from the upper end equal to its length, a crease 17 being formed across the center part on a line with slits 16. A continuation of slits 14 of the second mentioned blank is made at the upper end of the first. mentioned blank extending from crosscut 15 to slit 16'. This causes the ortion 18 included, Within a the dotted marg n to be cutaway. As the sponding depressions 20 on drum '8, the

lengthwise slits 14 being cut by knives 21 on, drum 8, said knives passing through the pa per into corresponding depressions 22 on drum 7.- The cross slits 11, 15 and 16 are cut by means of a knife 23 attached to a yielding slide 24 moving in guidest25 on a frame 26 centrally pivoted at 27 to standards 4. The end of frame 26 carrying slide 24 is held up by means of springs 28, and slide 24 is held against a flange 29, at the outer end of frame,26,-'by means of springs 30. The'end of frame 26 opposite slide 24 is provided with projections 31 adapted for engagement with cams 32, 33,34 and formed on the-ends of drum 8. Cams 32, 33 and 34 cause the ends 36 of knife 23 to cut slits 11 and 16 bypassing through the paper into corresponding recesses 37, 38 and 39 formed on drum 7. Cam 35 causes agreater downward movement of knife 23, which causes the center'40 of the knife, along with the ends 36, to pass through the pla er- 111110 a recess 41 extending'across the w o e face of drum 7, thereby making crosscut 15, the full width-of the-paper. Knife 23 is guided into recesses 37, 38, 39 and 41 by mea s of projections 42 formed on the ends 0. drum 7. When knife 23 comes in contact with guides 42, springs 30 will permit slide 24 carrying knife 23, .to move in unison with drum 7, until pins 43 riding against an inclinedface 44 formed onframe 26, causes the frame to move the knife out of engagement-with the paper and guides 42. hen knife 23 passes down through the paper, a stripper 45 on slide 24 is moved up in opposition to the forceof aspring 46, sothat when the knife is'lifted from the paper, the stripper will hold 110 let ' and a chain wheel 65.

flange 47- formed onthe-upper end of. the. stripper.

The cross creases 12 and 17 are formed as the paper passes between the drums 7 and 8 by means of short ribs48 on roller 7 placed between the-recesses 37, 38 and 39, which the ends 36 of knife 23 enter in cutting the cross' slits 11 and 16. Ribs'48 force the paper into corresponding depressions 49 formed on roller 8. "This crease 13 is formedby means of a rib 50 extendingacross the full width of the drum 7, said rib forcing the paper intoa corresponding depression 51 formed on drum 8.

Pins 52 on drum 7 pierce the forward end of the paper,so that after the knife '23 has cut off the paper blank the pins 52 will hold the paper against drum 7, therebyguiding the paper between the drums 7 and 8, and when the forward end of the passed between-the drums, the upper end of the chute will draw the paper away from the pins 52. p

In order that the cut away portion 18 of the paper shall not enter chute 9, pins 53 on drum 8 pass through the portion 18 into corresponding that as the the drums knives 21 alinement with chute 9, and permit it to slide off upon the incline 55.

To drum 8 is secured a shaft 56 which rotates in bearings on standards 4 and has a bevel gear 57 on one end in mesh with a bevel gear wheel 58 on a vertical shaft 59 by which it is driven. The opposite 'end of portion 18 passes from between 7 and 8, the pins 53 aided by shaft 56 has a gear wheel 60 attached, in

mesh with a gear wheel 61 on a shaft-62 secured to drum 7. Attached to gear wheel 60 is a chain wheel 63 which drives a chain 64 Chain wheel 65 is secured to .a shaft .66 carrying a roller 67 which turns in a paste reservoir 68. A series of indentations 69 are made in paste roller 67 near each end, which serve to carry paste from reservoir 68, to be taken up by paste wheels 70. The paste wheels 70 are mounted at thelowerend of a swinging frame 71 pivoted at 72. Paste wheels 70 are held against paste roller 67 by means of springs 73 acting on the lower end of swinging frame 71.

' The upper end of swinging frame}! 1 is'providedwith an extension 74 adaptedfor engagem'ent with cams 75 and 76 on gear wheel 61. By means of cams 75 and 7 6, paste wheels 70 are moved away from aste roller 67, into engagement with side aps of the blank as they pass down chute 9 Wheels 77 are so placed on the opposite side of the blank that the blank passes between paste wheels paper has holes 54 formed on drum 7, so

will carry portions 18 away from 70 and said wheels '77. Cam 75 causes paste wheel 70 to be held in contact with side .flaps 78 during their travel between wheels 70 and 77, causing paste to be applied throughout the length of side flaps 78, as shown at 79 in Fig 6. A break occurs before cam 76 'acts, causing paste wheel 70 to be moved awayfrom the center end flap 80.

Then as the flaps continue in their downward movement, cam 76 will cause paste wheel 70 to apply paste upon side flaps 81 for a distance equal to the width of the center end fla 80, as shown at 82 in Fig. 6.

The iilank as it passes from between drums 7 and 8 comes to rest on supports 83 at the lowerend of chute 9. The eentenof the blank then stands on a line with a channel 8 f forming part of a folding device 85. A reciprocating plunger 86 forces the blank through the folding device, causing the center end flaps S0 to be folded as shown in Fig. 7, the upper wide flaps 81 to be folded as shown in Fig. 8, and the lower side flap 78 to be folded as shown in Fig. 9. The paste applied to the side flaps causes the folded, flaps to adhere to each other.

By means of bevel gear wheels 57 and 58, vertical shaft 59 causes the rotation of shaft 56, and by means of gear wheels 60 and 61, shaft 56. causes the rotation of shafts 62. The bearings 87 of shaft 62 can be adjusted by means of screws 88, so that drum 7 can .be adjusted to suit the thickness of paper passing between drums 7 and 8. In mesh with gear wheel 61 is a pinion 89 secured to a shaft 90, to which Is seeureda fly wheel U1, the purpose of which is to ease the shock caused by knife 23 when. it strikes guides 4-2 and drum 7.
